Wish I could clear that up. If it was one of the other two roommates, don't know why they would say an unconscious person when there are four people dead/being killed.
From what the police chief says when questioned by the reporter, it does sound as though the 911 call came in reporting an unconscious person, rather than that the dispatcher has got crossed wires.
'You're right. But the report that we got was that it was an unconscious individual it wasn't until our officers arrived on scene, went in to do a caregiving check on the individual who was unconscious that we found the scene that was found'.
' We don't know why that call came in at noon and not in the middle of the night'
When he is asked how many other people were in the house who didn't get killed he says something else extremely odd:
'We believe two'.
I'm inferring from all this the following events:
The police had a report of an unconscious person and arrived on scene to do a care check. They found the door open [ETA: he mentions this earlier in the presser], so they entered the premises and instead found a gruesome murder scene.
IMO the other housemates were still asleep inside the house when the police arrived.
No one found an unconscious person and dialled 911. Someone outside the house dialled 911.
So the 911 call itself is suspect. And the housemates inside don't know how many people slept over that night.
